Abstract

In order to manufacture a radial tire, first, in an average waveform recording step, a waveform component of radial force variation (RFV) by a molding factor in each molding machine, and a waveform component of RFV by a vulcanization factor in each vulcanizer are respectively acquired and recorded in a computer. In a waveform synthesizing step, a radial run-out (RRO, that is, vibrations resulting from non-uniformity of a tire surface) waveform of a green tire is substituted by an RFV waveform component and is made to overlap with respective RFV waveform components of waveforms of a molding factor and a vulcanization factor, thereby obtaining an RFV composite waveform. In a selection step, a circumferential position on the green tire at which an amplitude of the RFV composite waveform becomes minimum, and the circumferential position in a vulcanization mold are selected. Further, in a vulcanization step, based on the selected circumferential positions, the green tire is disposed and vulcanized in the vulcanization mold. As a result, a radial tire of which RFV is sufficiently reduced can be obtained.
